Evaluations of the effectiveness of the near‐surface mounted steel materials in strengthening short RC wall‐like columns with openings

Structural Concrete, EarlyView.
Abstract In practice, reinforced concrete (RC) wall‐like columns often have openings to facilitate building services, which creates stress concentrations around the opening, resulting in the weakening of their load‐carrying capacity. This study proposes innovative strengthening methods using near‐surface mounted (NSM) incorporating steel materials to ...

On developing accurate prediction models for residual tensile strength of GFRP bars under alkaline-concrete environment using a combined ensemble machine learning methods

Case Studies in Construction Materials, 2023
GFRP (Glass-fiber reinforced polymer) bars are recognized as a structural material enabling replace existing steel rebar. However, GFRP bars exhibit a decrease in tensile strength under severe conditions such as strong alkalinity, high salinity, and ...

Prediction of shear capacity of concrete beams reinforced with glass fibre reinforced polymer (GFRP) bars / Noor Azlina Abdul Hamid [PDF]

, 2018
Steel reinforcement bars are one of the most common reinforcement materials used in concrete structures for many decades due to their high tensile strength and modulus of elasticity.

Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

Structural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

Effect of Designed 3D Reinforcement in Mitigating Machining Damage on CFRP Plates

Polymer Composites, Volume 47, Issue 7, Page 6773-6784, 10 April 2026.
Effect of Edge Tufting on Surface Quality, Damage, and Mechanical Performance in CFRP Machining: A Comparative Topographical and Structural Analysis. ABSTRACT Composite materials made of carbon fiber‐reinforced epoxy (CFRP) are widely used in aerospace fields due to their high strength‐to‐weight ratio. However, due to low out‐of‐plane resistance, these

Post‐Consumer Mechanical Recycling of Thermally Degraded Glass‐Fiber Reinforced Polyamide 6,6 for Electrical Applications

Macromolecular Materials and Engineering, Volume 311, Issue 4, April 2026.
Post‐consumer mechanical recycling of PA66–GF composite with brominated flame‐retardant is assessed using accelerated thermal ageing to reproduce long‐term thermo‐oxidative degradation typical of electrical devices. Property retention is quantified across virgin, aged, recycled, and diluted recycled states through mechanical testing, microscopy, DSC ...

Structural Behavior of Reinforced Concrete Columns Fully and Partially Reinforced with GFRP Bars Tested Under Concentric or Eccentric Compressive Loads

Diyala Journal of Engineering Sciences
Concrete columns reinforced with glass fiber-reinforced polymer (GFRP) bars have been greatly interesting recently. The distinct properties of GFRP bars, such as high tensile strength and low modulus of elasticity compared to steel bars, as well as the ...
